Description

  The present invention relates to a formwork apparatus used for molding a retaining wall block or the like.

  In general, a block forming mold apparatus is joined to, for example, a front part mold member and a pair of two sides of a front part mold member when a concrete material is filled from the back side of a product block. Formed from an upper surface formwork member and a lower surface formwork member, and a left side surface formwork member and a right side surface formwork member joined to another set of two sides of the front surface formwork member The length dimensions of the upper surface part formwork member, the lower surface part formwork member, the left side face part formwork member and the right side face part formwork member are fixed to a fixed dimension, and the product block The dimension between the front plate portion and the back plate portion, that is, the reserved length is fixed.

Up to now, when manufacturing several types of blocks with different reserve lengths, it is necessary to prepare and prepare a dedicated formwork device corresponding to the reserve length, which increases the capital investment related to the formwork. .

As shown in Patent Document 1, it has also been proposed to form several types of blocks having different lengths while using the same basic formwork.
This is a mold for pouring concrete to produce a PC foundation, a base portion that is long in one direction that defines the bottom surface of the poured concrete, and a frame body that holds the concrete in a predetermined shape on the base portion. The frame body includes a pair of end frames that hold both ends of the base portion in the longitudinal direction, and an intermediate frame provided between the pair of end frames. At least one of the pair of end frames moves in the longitudinal direction on the base portion according to the length of the PC foundation to be manufactured, and the intermediate frame has a length corresponding to the interval between the pair of end frames. Have.

  This method is effective for the production of solid blocks with a uniform product cross-section, such as Kintaro Samurai, but for the production of hollow retaining wall blocks with a non-uniform internal shape and cross section. It cannot be applied.

JP-A-8-11119

  It is an object of the present invention to provide an improved mold that can easily produce a plurality of types of products having different holding lengths and can reduce equipment costs related to a formwork even in a retaining wall block whose internal shape and cross section is not simple. It is to provide a frame device.

  The formwork apparatus of the present invention is additionally used for forming a basic formwork used for forming a basic mold block having a minimum reserve length and a stretched mold block whose reserve length is extended from the basic block. The lap joint mold has the same cross-section as the basic mold and has a length corresponding to the difference in the length of the basic mold block and the stretched mold block. The basic mold is aligned in the reserved length direction and bonded and fixed to the basic mold.

In the mold apparatus of the present invention, in forming the stretchable mold block, it has the same cross section as the basic moldwork and has a length corresponding to the difference in the reserved length between the basic mold block and the stretchable block. Since the joint molds are aligned and fixed to the basic molds in the reserve length direction of the basic molds, a plurality of types of stretchable blocks having different reserve lengths can be easily manufactured.
Although it is necessary to prepare for the production of lap joint molds according to the difference in the reserve length, the amount of material used is significantly reduced compared to the case of preparing the entire formwork with different reserve lengths. The labor cost of the company will also decrease, so the capital investment related to the formwork can be greatly suppressed.
